Name for Horse

I'm writing a book about a girl named Rose Zales. She sees a movie called Dakota Boots where Dakota, the main character, has a chestnut brown horse. I've never owned a horse, so I don't know of any good names. Could you guys think of some? Thanks a bunch! -Ninas1

How about something obvious, like Chestnut? Or Hazel, so it's somewhat related but not as obvious. Just think of pet names, like what would you name a dog of that color? I'm not a big horse person either, but those are my suggestions.

“I read books when I was a kid, lots of books. Books always seemed like magic to me. They took you to the most amazing places. When I got older, I realized I couldn't find books that took me to all the places I wanted to go. To go to those places, I had to write some books myself.”
